Interestingly, there are three .rc files for windows that I can see, two of them are properly updated and just this one is not. Of course this is the one used when building the dll.

A problem that could stem from this is Installers, if they compare those values to determine whether to update the file or not, some may not update the file if the user has v. 1.2.2 on the machine. Any other existing version will still get updated.

They must know and have chosen not to do anything about it. They have to know since GNUWin32 has "fixed" theirs for their build. I would think they would have mentioned it to the author/s.
